Dowel angled drilling jig for tripod (model rocket stand)

thingiverse

This is meant to be a jig for drilling a (larger) dowel at a shallow angle in order to make a tripod by inserting (smaller) dowels. The original purpose is to make small stands for model rockets. I imagine the plastic will get chewed up pretty quickly, but it might be good for a few stands. Attached example STL is for a 25mm (1 inch) dowel being drilled to receive three 10mm (3/8") legs. Attached pictures are for a 5/8 main dowel, 5/16 legs, at 25 degrees, up 6mm from the bottom. Floor and wall are 8mm, the top socket is 30mm deep. 15% infill, but three perimeters and three layers top and bottom. You can set how many holes it prints. Default is all of them; the code has "360" set which functionally ensures all holes are printed. Two is technically enough (stick a peg in the first hole and rotate the jig). Customizable for size and number of legs, angle of legs (even negative, if you want to make a grappling hook, say), and other structural parameters (wall thickness, etc.). It's all marked up for the Customizer app but I definitely recommend just opening the SCAD file in OpenScad instead. Some takeaways from my first attempt: -Make sure the holes print big enough - remember circles tend to shrink in FDM printing. I had to carve mine out a tiny bit with a forstner bit. -Use a depth stop collar/flag when drilling. My holes touched inside and my legs were slightly different lengths. -Shallower angles are better (a steep hole has to get pretty deep before the top edge cuts) -Bigger differences in size between body and legs are better
